What is the term for the maximum permissible exposure limit in laser safety?

Explanation:
In laser safety, the key idea is identifying the highest level of laser radiation to which a person can be exposed without expected harm for a given wavelength and exposure duration. This is known as the maximum permissible exposure, abbreviated MPE. Standards such as ANSI Z136 and IEC 60825 define it and tailor it to factors like wavelength, exposure time, and whether the exposure is ocular or dermal. The MPE guides what protective measures, engineering controls, and safety procedures are required, helping to set safe working limits. Other terms listed don’t reflect the standard terminology used in laser safety; they aren’t the recognized label for this exposure threshold.
